To all whom it may concern:

Be it known that I, NORDAL MIKELSUN, a citizen of the United States, residing at -Meckling, in the county of Clay and State illustrating the means by which the husking rolls are held in contacting relation;

Fi 5 is a fragmentary view, in elevation, further illustrating the part shown in Fig. 4t;

Fig. 6 is a detail cross sectional view of oneof the husking rolls; and

Fig. 7 is a detail longitudinal sectional view illustrating the manner in which the husking pins are mounted.

Like numerals of reference designate like 01 corresponding parts throughout the several views.

- Coming now to a detail description of the machine, 1 designates the main frame of the machine and 2 an auxiliary frame supported in spaced relation thereabove through the medium of supporting brackets 3. The main frame 1 is mounted on supporting wheels & and is adapted to be drawn along behind a wagon 5 into which the elevated end of aconveyer designated as an entirety .by the numeral 6 discharges. Any suitable means such as a draft tongue 7 may be utilized to fasten the wheeled supporting frame or the corn husking-machine to the wagon 5.

A trough like inclined hopper 8 is .mounted above the mainframe 1 and the auxiliary frame 2, standards or uprights 9 affording .a support means for the hopper sides. -,A deflector plate 10 is fastened in any suitable manner to one of the hopper sides thatthe corn directed or thrown in the general direction of the hopper may be deflected and consequently directed thereto.

A suitablefeed conveyer 11 is mounted to o' erate at thebase of the hopper to convey t e corn directed thereto upwardly at an .be driven as hereinbefore stated.

inclination and to an opening 10 formed in the hopper base at the elevated end thereof.

Beneath the hopper 8 is arranged a secondary hopper 12 the sides of which engage with the uprights or standards 9 that the hopper as an entirety may be held or supported against n'iovcment.

Husking rolls 13 and 14L are mounted to extend longitudinally of the hopper 12 and in parallelism, one of said rolls being directly driven in the manner hereinafter fully described and the other of said rolls, by reason of its engagement with the roll first mentioned, rotating in a cmmter-direction. Roll 13 is mounted on a shaft 15 journaled in the machine f nine 2. A bevel gear 16 is mounted at one end of the said shaft 15 to mesh with a like gear 17mounted on a shaft 18 journaled in brackets 19 fastened to the rear end of the auxiliary frame 2.

The shaft 18 carries a sprocket 20 over which a chain 21 operates to drive a second sprocket 22 mounted on a shaft 23 journaled in bearings 24 secured to the main frame 1. The shaft 23 is driven to operate the conveyer 6 which, as shown to advantage in Figs. 2 and 3 is located at one side of the main frame and within a conveyor frame 25 therefor. Said conveyer 6 is mounted to operate at an angle or inclination to convey husked corn upwardly to a point of dis charge directly above the wagon box or container 5.

Shaft 18 is equipped at one end with. a pulley 26 over which a belt 27 operates, the said belt being crossed and driven through the medium of a pulley 28 in turn driven by an engine 29 (preferably of the internal combustion type) mounted on the main frame 1.

Said shaft 18 is further equipped with a sprocket 30 over which a chain 31 operates, the said chain engaging with a sprocket 32 on a shaft 33 that the feed conveyor 11 may By the above arrangement it is evident that the feed conveyor 11, the huskingrolls 13 and 14, the conveyor 6 and a reciprocatory shuttle board or blade 34 (subsequently to be described) are all driven by the engine 29.

Upon the opposite end of the shaft 15 from that supportingthe bevel gear 16 is mounted a like bevel gear 35, this last mentioned gear being in mesh with a bevel gear 36 mounted on a shaft 37 journaled. in brackets 38 secured to the auxiliary frame 2. Said shaft 37 is provided with a crank terminal 39 over which one end of a reciprocatory rod 40 is mounted, the said rod receiving its ,reciprocatory movement by reason of its engagement with the crank terminal 39 just mentioned. Said rod 40 at its opposite end is in engagement with gagement with the corn acted on. I Shaft 15, at a point'in proximity to the gear 35 mounts a sprocket 46 over which a chain 47 operates to drive a sprocket-48 mounted on a shaft 49 extending in parallelism with the shaft 15 the'reabove. Said shaft carries at its opposite end what may be termed a kicker-disk 49 from which a pin 50 projects,'the said pin being rotatable to engage with and elevate or throw the husked corn that the ears may be directed through an opening'51 in the hopper 12. A chute 52 is arranged over the opening 51 to convey the'husked corn to the elevator or conveyer 6 previously described.

Husking roll 14, or rather the shaft 53 which acts as a support therefor is mounted to move relatively to the auxiliary frame that the roll 14 may be held in yielding contact with the roll 13 which is rigid. A

pressure roll 54, spring pressed as indicated at 55 is mounted to engage with the roll 14 to thus hold the two husking rolls in yielding contact or in engaging proximity. This I arrangement will permit relative movement of the roll 14 should the machine for any reason fail to remove the husks and cause an ear of corn to be forced between the husking rolls'. Such arrangement will preclude breakage under normal operating conditions.

Each huskingv roll is equipped with a plurality of transversely extending hollow pin tubes 56, the mentioned tubes being exteriorly threaded at one end or as indicated at 57 to engagewith the roll itselfJ Said tubes are thusheld in place. Vithin each tube 56 thus mounted is disposed a husking pin 58, the said pin being adapted for.move ment relatively to the tube 56, such movement being against tension of a spring 59 located int'eriorly of the tube and abutting at one endastop pin 60 and at its opposite the hopper 12 and against the husking rolls.

The mentioned rolls being set to operate at an-inclination it is apparent that the corn or cars will gravitate towardthe lower end of said rolls, and through operation of the husking pins 58 and the shuttle 34, is so treated or acted on as to cause the husks to be entirely removed: The removed husks will fall or gravitate to a point below the husking rolls where they may be collected in any suitable manner. The husked com,

finally reaching the lower end of the husk- 7 ing rolls, will be engaged by the kicker-pin 50 and through such engagement directed to the opening 51 and thence by the chute 52 to the conveyer 6. From the conveyer the husked corn is carried upwardly and into the wagon box or container I amaware that corn husking machines have been heretofore provided embodying shuttles mounted for movement adjacent the instance the shuttles have been mounted for movement in a plane at right angles to the plane of inclination of the husking rollers and not in a plane parallel to the plane of inclination of the rollers, as in the machine of my invention described above; Owing to this arrangement, that is the mounting of the shuttle for movement in a plan parallel to the inclination of the shuttle of the husking rollers the ears of corn, after being partly rotated by movement of the husking rollers, in the usual manner, are engaged by the shuttle, thereby slightly dislod'gin'g' the ears so as to rotate them slightly topermit I husking rollers, but to my knowledge in each the studs of the husking rollers to engage other portions of the fhusks whereby to effectively remove the husks before the ears arrive at the lower end of the machine. The ears are thus subjected to ,aslight rolling motion by the engagement therewith of the shuttle tending to force the ears from the rollers, which tendency is offset bytherotation of the rollers to maintain theear in a position between the rollers. In machines of the character heretofore'providedwhere sure the removal 0 a11 thehusks-.-

From the foregoing, taken in connection with the accompanying drawings it is apparent that the several mechanisms involved may all operate, and operate properly, through the agency of a single engine or other power means; that the various component parts are so arranged relatively to the supporting frame 1 as to occupy a minimum of space and permit of access should repair make such access necessary; and that the shuttle, by reason of its location above the husking rolls will contact with the ears of corn and to a material extent loosen the husks that they may be later removed by the husking pins 58.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efiicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claim.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

In a corn husking machine, the combination of a frame, a pair of inclined husking rollers in horizontally spaced relation, a reciprocablc shuttle in the form of a flat bar disposed upon the rollers in parallelism thereto and having one longitudinal edge serrated and said edge located above the space between the rollers, a pair of links pivotally mounted at one of their ends upon the frame for supporting the shuttle upon their opposite ends, means for vibrating said shuttle across the upper face of said rollers and in a plane parallel to the plane of the inclination thereof.

In testimony whereof I aifix my signature in presence of two witnesses.
